joined to a collecting duct, which carries urine through the medulla
to the pelvis of the kidney.
Each Bowman's capsule is supplied with blood by an afferent arteriole.
It branches inside the Bowman's capsule to form a knot of capillaries,
the glomerulus. These join up again to form the efferent arteriole,
which take blood away from the Bowman's capsule. The afferent
arteriole is much wider than the efferent arteriole; this means that
pressure is built up.
Ultrafiltration involves the filtering (under pressure) of small
molecules out of the blood and into the Bowman's capsule. The blood
entering the glomerulus is separated from the space inside the
Bowman's capsule, by two cell layers and a basement membrane.
* The first layer is the endothelium of the capillary. In the
glomerulus, this single layer of cells has thousands of gaps.
* The basement membrane between the two cell layers is composed of
glycoprotein and collagen fibres. Its mesh-like structure acts as
the filter during ultrafiltration.
* The second layer makes up the wall of the Bowman's capsule.…
The kidneys function to filter both toxins and additional not needed water. Kidneys have tons of nephrons which are tiny filters. A nephron is made up of two parts which are the glomerulus and the tubule. The glomerulus filters large molecules and blood cells from liquids and toxins. Then the filtered liquids and toxins go to the tubules. The tubule filters out more toxins missed from the glomerulus. It also gathers minerals and releases them back into the bloodstream. During the…
Briefly trace and discuss the flow of blood in the human kidney.
Blood passes into the kidney through the renal artery entering the glomerulus within the Bowman’s capsule. However, when traveling into the glomerulus it is split into fifty capillaries, which has thin walls. The solutes within the blood are filtered through the thin walls by the pressure gradient exiting between the fluid in the Bowman’s capsule and blood capillaries. The pressure gradient is regulated by the dilation or…
their axons through the cribriform plate to the glomerulus, which is a spherical structure found in the olfactory bulb (OB). OSNs are part of the olfactory neuroepithelium alongside sustentacular cells (for structural support) and basal cells (stem cells by which new OSNs are generated).
In the glomerulus, odor related information are transmitted to mitral/tufted (MT) cells which are second order neurons. These neurons are extensively regulated by intrabulbar circuits as well as centrifugal…
Glomerular filtration is the physical method the kidney uses to sort what should be excreted from what should be kept in the bloodstream. In the first part of the process, a membrane called the filtrate membrane filters out red blood cells, large proteins, and other large plasma solutes. For example, albumin is filtered out at this point, with only a tiny amount remaining in the subsequent glomerular filtrate. Because the afferent arteriole to the glomerulus is much larger than its efferent…
The urinary system functions to removes wastes from the blood and the kidney is known for filtration and absorbing water. The urinary system consists of a renal corpuscle (glomerulus and bowman’s capsule), a proximal tubule, a loop of Henle, and a distal tubule.
The kidney filters about 180 liters and gets rid of about 1.5 liters as urine. Renal clearance is a measurement that analyzes the activity and efficiency of the kidney; it is the volume of plasma need for the kidney to complete remove a…
often over looked. The urinary system removes toxins from the blood and maintains the acid-base balance of the body. This system regulates the chemical composition, volume, and electrolyte balance of the blood. The urinary system works in with the respiratory, integumentary, and digestive organs to eliminate waste. Reflexology supports and enhances the urinary system by removing toxins that help reestablish balance. In this paper, I will go over three important facts about the urinary…
f. Describe the histology and gross structure of the kidney
g. Describe the detailed structure of a nephron and its associated blood vessels
h. Describe and explain the production of urine, with reference to the processes of ultrafiltration and selective reabsorption
1. Blood flows into the glomerulus from the afferent arteriole which is wider than the efferent arteriole which carries the blood away from the glomerulus.
2. This means that the blood in the capillaries is…
(one if you have a horseshoe shaped kidney) which are a reddish purple colour and bean shaped. These are located below the ribs towards the middle of the back.
Their job is to regulate blood pressure, remove liquid waste from the blood in the form of urine, keep a stable balance of salts and other substances in the blood, and produces a hormone erythropoietin that aids in red blood formation.
Bowman’s capsule - Surrounds a glomerulus and captures its fluid.
Carrying tube - Carries fluid…
acute kidney failure can be caused due to sudden renal injuries or by systemic diseases of the body. The major issue with acute renal failure is the fact that the kidneys filter the blood so it is linked to every other part of the body and can spread diseases more readily which could make it easily life threatening (Huether & McCance, 2012, page 741).
Some of the non-modifiable disease processes that cause acute renal failure are glomerulonephritis, rapidly progressive glomerulonephritis…
